4th Grade students will be able to:
Know relative sizes of measurement units within one system of units including standard units (in., ft, yd, mi; oz., lb; and c, pt, qt, gal), metric units (cm, m, km; g, kg; and mL, L), and time (sec, min, hr, day, wk, mo, and yr). Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. A table of equivalencies will be provided.
Example 1: Know that 1 kg is 1,000 times as heavy as 1 g.
Example 2: Express the length of a 4-foot snake as 48 in.
Use the four operations to solve word problems involving distances, intervals of time (such as elapsed time), liquid volumes, masses of objects; money, including problems involving simple fractions or decimals; and problems that require expressing measurements given in a larger unit in terms of a smaller unit.
Apply the area and perimeter formulas for rectangles in real-world and mathematical problems (may include finding a missing side length). Whole numbers only. The formulas will be provided.
Identify time (analog or digital) as the amount of minutes before or after the hour.
Example 1: 2:50 is the same as 10 minutes before 3:00.
Example 2: Quarter past six is the same as 6:15.
Make a line plot to display a data set of measurements in fractions of a unit (e.g., intervals of 1/2, 1/4, or 1/8).
Solve problems involving addition and subtraction of fractions by using information presented in line plots (line plots must be labeled with common denominators, such as 1/4, 2/4, 3/4).
Translate information from one type of display to another (table, chart, bar graph, or pictograph).
Measure angles in whole-number degrees using a protractor. With the aid of a protractor, sketch angles of specified measure.
Solve addition and subtraction problems to find unknown angles on a diagram in real-world and mathematical problems. (Angles must be adjacent and non-overlapping.)
